Using a Z-Wave programmer (aka a master controller), you can essentially flip the switch's software (if you installed it upside-down, intentionally or accidentally, the software can compensate for that). Also, the LED indicator can be programmed to turn on when the light is on, which is very useful for lights you can't see - ie outdoor lights.

Pros

Pro

Internal breaker

This switch incorporates an internal breaker, protecting the light from power surges.

Pro

Inconspicuous design

Once installed, these look like just any regular old light switch. They will fit into any house just fine without drawing any attention to themselves. It's the best way to upgrade the tech in your house without changing the way it looks at all.

Pro

Programmable

Also, the LED indicator can be programmed to turn on when the light is on, which is very useful for lights you can't see - ie outdoor lights.

Pro

Touch controls

Tapping the switch will toggle the lights on/off, and long touching will slowly brighten or dim the lights.

Pro

Small LED indicator

There is a small blue LED indicator on the bottom right of the switch. By default, it turns on when the light is off, allowing you to easier see where the switch is in the dark. If you have a Z-Wave programmer however, you can change it to be the opposite - when the light is on the LED is on. This can be useful for lights outside, or other situations where you can't immediately tell if the device is on or off.

Cons

Con

No instant notification

This switch doesn't automatically update the system when it activates or deactivates, meaning the controlling system won't know if the switch is activated or deactivated until it polls each device itself. This means that if the switch is actuated manually, your app won't know that the light is on.

Con

Limited temperature range

This switch is only meant to be used from 32-104 Fahrenheit (0-40 Celsius). This switch may fail if installed in an unheated garage, or during a power outage in the middle of winter.

Con

Installation can be difficult

If you haven't swapped out wall switches before, it can be tricky. You will have to un-wire the old one, and wire the new one to the existing wires. The instructions use some jargon that isn't explained, which you will need to figure out before the instructions make any sense ('line' means the wire coming from the breaker, 'load' means the wire going to the light fixture, and 'traveler' means the wire(s) that runs between multiple switches that control the same light.

Con

House wiring requires neutral wire

The neutral wire is needed for this wall switch - it simply won't function without it. Older houses may not have the wiring required for these switches to work.
